Chris Hemsworth calls out Liam Hemsworth on his near-nude Insta pic – like only a big bro can

And now, it would seem, big bro Chris Hemsworth has shed new light on the instantly iconic image.

According to the 33-year-old Thor star, young Liam's revealing Instagram post (which showed him wearing a pair of tiny boardshorts and flexing in an ice bath) was possibly the result of a few too many alcoholic bevvies!

"You know what that felt like?" Chris said at a fashion event in New York on Wednesday. "That felt like a late Friday night, drunken kinda post."

Indeed, Liam's caption ("Here's to ice baths and flexing in tiny shorts") did sound a little out of character for the notoriously private Hollywood actor.

And according to Chris, who was in the Big Apple to attend the Boss Menswear spring/summer show after being announced as their newest ambassador, his little bro suffered major post regret the next day.

Unlike the rest of us regular mortals, by the time 27-year-old Liam sleepily rose from bed, his "tiny shorts" had done the rounds on the internet. And the snap? It had gained a respectable 400,000 likes.

The father to India Rose, 4, and twin sons Tristan and Sasha, 2, with wife Elsa Pataky, went on to shut down any rumours of competition with Liam.

"People try and pair us off like there is this type of vicious tension and competitiveness, like 'Oh, you got that part and I didn’t', which is not the case," Chris said.

"If you get us at home playing cricket or football or surfing, there is a great rivalry there, very healthy one, but not with work."
